Application filed April 15,

r This invention relates to a truck conveyer of that type which is adapted for receiving material at one end. and conveying it to a higher elevation.

it is among the objects of this invention to provide such a conveyor in which the lower end of the boom may be positioned at a pre determined point, for example, under a, coal car for conveying the coal therefrom to a higher elevation, in which the inclination of the boom may be varied without a displacement of the lower end and in which the variation in the inclination of the boom does not affect the driving relation between the power means and the conveyer on the boom.

In its broadest aspect, this invention con sists of a conveyer boom mounted upon a support which is so connected to the boom as to be movably responsive to variations in the inclination of the boom, for maintaining the lower end thereof at a predetermined point, and in which the driving mechanism for the conveyor on the boom is likewise responsive to variations in the inclination of the boom for maintaining an effective drive for all inclinations of the boom.

The objects of the invention are preferably accomplished by the use of a rolling and pivotal support, which is so connected to the boom that any variations in the inellnation of the latter is adapted to roll and tilt the suport.

"With these and other objects in view which will become apparent in the following description and disclosures, this invention comprises the novel structure and combinations of parts hereinafter described and more particularly pointed out and defined 1n the appended claims.

As shown on the drawings:

In the illustrated embodiment of this invention, the aforementioned pivotal and rolling support consists of a transverse member 1, to each end of which a rolling element in the form of a wheel 2 is swiveled by means of a suitable knuckle joint 3, as shown more clearly in Figure 10. The support further comprises a motor platform t and upright members 5, which in connection with the member 1 form a substantially bifurcated structure or standard for receiving the conveyor boom 6. This structure affords a movable or shiftable fulcrum member for the boom, in that the same is supported thereby in inclined position as shown in Figure 1. To this end, a cable pulley 7 is j ournaled on the upper end of each side member 5. A cable 8 is trained over each pulley 7 and over a grooved roller 9. The rollers 9 are secured upon the ends of a shaft 10 which is secured to the bottom of the conveyor boom by means of suitable bearings 11 as shown in Figure 3. As the cables 8 pass over the rollers 9, they are anchored to suitable hasps 10 on the side members 5 as shown in Figure 2. These cables extend downwardly, one passing under a guide roll 12, on the transverse member 1 and around a drum 13 shown more clearly in Figure 4. The other cable 8 passes around a coaxially arranged drum 14:. It will, of

- course, be understood that the ends of the cables 8 will be finally attached to their respective drums. The drums 13 and 14 are secured upon the ends of a shortshaft 15 which is journaled in a suitable casing 16 on the base support 1. A worm gear 17 1s keyed upon the shaft 15. This worm gear is adapt.-

' ed tobe driven by a worm 18 which is secured upon a shaft 19 which iscoupled by means ofa universal joint 20 (Figure 3) to a vertical shaft 21. The upper end of the vertical shaft 21 is provided with a pinion 22 adapted to be driven by either of the pimons 23 or 24 secured upon a short transverse shaft 25.

It will be noted With reference to Flgure 3 that one upright member 5 is re nforced by a sloping upright member 5", which extends from the transverse member 1 to the top of said member 5. The other transverse member is reinforced by an upright member 5*, which extends in parallel relation to its memher 5 to a point above the shaft 25, at which point there is a sloping brace 5 that connects with the member 5 and the ad acent member 5". The upright members are also reinforced by the bowed struts 5 which he 1n the same longitudinal plane as the members 5. The aforementioned upright shaft 21 1s ournaled in a bearing 26 which is slidably mounted upon an upper flanged transverse brace 27 extending between the members 5 and 5". To this end, the bearing 26 is provided with a flange 28 that rests upon the upper flanged transverse member 27. The flange 28 1s provided with slots 29, for receiving studs 30, extending from the flange of the upper flanged transverse brace 27. The bearing member 26 is provided with suitable cars 31 to whlch a link 32 is connected. The outer end of this I link 32 is connected to a crank on a rod 33 geared to a sprocket 39 on the shaft by means of a suitable sprocket chain 40. The sprocket wheel 39 is provided with a clutch hub 41 which is loosely mounted on the shaft 25 and is adapted to be clutched thereto by a suitable clutch member 42. The shaft 25 is the main driving shaft of the machine, as will later more fully appear.

The boom is connected to the upright support by suitable link members'npon each side thereof. A pair of links 43 which act as radius rods are pivotally connected at their forward ends to the lower portion of the conveyer boom, by means of a rod 44. The rear ends of the bars 43 are suitably pivoted upon nvlaeio the transverse member 1 in order that said bars may pivot or swing with respect thereto. Toward the upper end of the boom there is secured a transverse shaft 45, the ends of which project beyond the sides of the boom as indicated in Figure 9. A link 46 is pivoted at one end to one end of the shaft 45. The other end of this link 46 is suitably pivoted to the upright support upon an axis 47 which is coincident with the axis of the main driving shaft 25. Upon the opposite side of the boom a second link 48 is pivotally attached at its upper end to the shaft 45. This link 48 is provided with diverging arms, the lower ends of which are secured in rotatable sockets 49 (Figures 3, 5 and 11) which are respectively secured upon the uprights 5 and 5". be noted that these sockets have circular slotted portions 50,-which extend around a hearing 51, in which the aforementioned shaft 25 is journaled, consequently, the lower pivot points of the rod 48 lie in the axis of the shaft 25. These bearings are attached to the upright members 5 and 5 by means of U -shaped bolts 52. A form of cam member 53 is slipped over the ends of the U-shaped bolt and extends through the slot of the circular part of the socket member 49 for maintaining the parts in proper assembly.

The boom 6, which may be of any suitable construction, preferably consists of spaced upper and lower angle members 54 which are connected by metal lattice work 55. A lower series of rolls 56 is supported from the lower angle members and series of rolls 57, 58 and 59 (Figure 9) are supported upon the upper angle members 54. The upper rolls are preferably supported in a casting 60 which is provided with spaced arms 61 for receiving the pintles of the rolls, which are arranged in dish-shaped relation. The upper and lower series of rolls support an endless conveyor 62 which may be of any convenient designf This conveyer passes over suitable terminal pulleys 63 at the ends of the boom. The upper pulley 63 is geared by suitable sprocket gearing 64 to the shaft 45 and the shaft 45 is geared by suitable sprocket gearing 65 to the main driving shaft 25 which is provided with a suitable sprocket gear 66 loosely mounted upon the shaft 25 but adapted to be connected therewith by means of jaw clutch member 67 engaging the aws on the hub of said sprocket. The clutch member 67 is provided with a groove 68 for engaging a bell crank shipper lever 69 to which a link 70 is connected by means of which the bell crank may be operated for disengaging or engaging the clutch. It will he noted that the link 48 and the companion link 46 connect the axis of the sprocket 66 and the sprocket 71 of the aforementioned sprocket gearing 65 on the shaft 45. Consequently, the two driven members 66 and 71 are always spaced a constant distance irrespective of the inclination of the boom.

It will In the operation of this conveyer it isadapted to be manually moved in position. If it is desired to unload a car of coal, the lower end of the boom will be placed beneath the discharge hopper of the car. This boom may extend for 40 feet or more to a truck or coal bin or the like for transferring the coal thereto. In order that the discharge end of the boom may be at the proper elevation for the truck or bin or the like it may be raised or lowered. When it is desired to raise or lower the boom, the clutch member 67 is preferably disconnected from the sprocket drive and the rod 33 is operated for shifting the gear 22 into engagement with one of the pinions 23 or 24according to whether it is desired to raise or lower the boom. then started, the rotation of the shaft 25 will rotate the vertical shaft 21 for rotating the drums 13 and 14 in the proper-direction for lowering or raising the boom. During the raising and lowering of the boom the connecting links 43,46, and 48 will tend to tilt the boom support as shown in dotted lines in Figures 1 and 2.

If the rolling support for the boom is maintained stationary during the raising or lowering of the boom, the front end of the boom will naturally change its position as shown in Figure 1; however, the front end of the boom may be anchored in a predetermined position. In such case, the supporting standard for the boom will not only tilt as shown in the drawing, but will also be compelled to move upon the rolling elements 2 when the inclination of the boom is varied. The link members 43 and 46 act substantially as a couple and cause a movement of the boom support.

It will be appreciated that during all adjustments of the boom, the driving shaft 87 of the engine, and the main driving shaft 25, will be spaced a constant distance. Likewise, the driving member 71 and the sprocket 66 will remain at a constant distance. While it is necessary that the supporting frame of the boom shift during a change in the inclination of the boom, this shifting does not in any way affect the driving relation between the conveyer and the engine.

It will further be appreciated that in the use of this conveyer it is possible to position the feeding end of the conveyer at any predetermined desired point, and it is possible to vary the inclination of the conveyer without disturbing the feeding end of the conveyer. It is also possible to turn the wheels 2'transversely and roll the boom to change the position of the discharge end without mateiilally changing the location of the lower en It will also be appreciated that during any such variations in the inclination of the boom, the drive between the conveyer and If the engine is I a fixed relation, irrespective of the position likewise responsive to the-same movements.

Consequently, the conve er drive is never afi'ected by any change in t e position of parts.
